Wireless screen sharing from a Chromebook/laptop to a Promethean ActivPanel Elements series interactive display

Enables teachers and students to wirelessly cast their laptop screens to classroom ActivPanel displays without cables, facilitating collaborative classroom interaction from anywhere in the room

1. User clicks extension icon to open popup. 2. User enters the Panel ID displayed on the Promethean ActivPanel. 3. User enters their display name. 4. User enters a waiting room while the ActivPanel teacher selects up to 4 screens to share. 5. Once approved, user's screen is cast wirelessly to the ActivPanel via WebRTC. 6. User can stop sharing at any time.

Target users: Teachers in K-12/classroom environments / Students in classroom environments / Schools using Promethean ActivPanel Elements series hardware

Source code is heavily minified/webpack-bundled, limiting deep code inspection
The 'login' keyword match in the heuristic came from the store description context ('No sign in required') which actually confirms no login needed—false positive from keyword-only matching
Cannot verify if the ActivPanel hardware or mypromethean.com service discovery endpoint requires a Promethean account at the device level

Monetization

No paid features detected

No payment platforms, no premium tiers, no subscription logic, no billing UI, and no feature gating found in source code. The 'pro' keyword matches are all from the 'Promethean' brand name in locale files, not a 'pro' tier. The Promethean ActivPanel hardware is a separate paid product, but the extension itself is free and un-gated.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: Store description explicitly states 'No sign in required.' Source code contains no login UI, no OAuth flows, no credential collection. The 'logined' state in EStates enum (background/index.js line 1) is an internal bitmask flag for WebRTC connection state tracking, not user authentication. Users connect by entering a Panel ID displayed on the physical ActivPanel and a display name—no account needed.
